2 Administration and Projects Committee STAFF REPORT September 1, 2016 Page 2 of 2 Background In April 2015, the Authority approved Cooperative Agreement No for construction of the SR4/Balfour Road Interchange project. Under the Agreement, the Authority will Advertise, Award and Administer (AAA) the construction contract with the California Department of Transportation (Caltrans) providing project oversight services. In July, 2014, the Authority approved Agreement No. 404 with PSOMAS to provide CM services for the SR4/Balfour Road Interchange project as part of its obligation under the Cooperative Agreement. At that time, the project was expected to advertise for construction bids in Due to complex ROW negotiations the project has been postponed and is expected to begin construction in Fall PSOMAS has been active in the utility coordination and construction of a joint utility trench since Currently, PSOMAS is performing inspection services that are scheduled for completion in October The work was initially scheduled for 6 months and is now expected to take a total of 16 months. In addition, the original agreement assumed that the Relocation and Remediation (R&R) of the Kinder Morgan (Kinder) pump station would be constructed concurrently with the joint utility trench. Due to the issues surround by the ROW, the R&R is anticipated to begin in the Fall of 2016 during the construction of the project. A portion of this work will be completed at night, increasing the level of effort required from the CM team. Since the original agreement was executed, several assumptions have been adjusted. The Authority has requested that PSOMAS provide biological monitoring and mitigation work while the project is under construction and this increase of scope has been added to the proposed amendment. Also, the project has been extended by 20 working days and the staff pay and overhead rates have been updated to their current values
